I may want to translate all the italian comments for my own edification but here is the translation for the title, it's and old Italian syaing: If you don't go you won't see, if you don't see you won't know, if you don't know you'll take it in the ass every time.
My own comments in english: It's a shame she didn't swallow being that she was otherwise a perfect slut and a good cockwhore. I guess some directors do that for the money shot though??
